Abstract

L'invention concerne une pompe seringue classique (10) utilisée pour distribuer des liquides en volume inférieur à 5 νl dans un ensemble de distribution (1). Une barrière de séparation formée par une membrane élastomère souple (5) est logée entre une partie intérieure (3) et une partie extérieure (4) d'un distributeur (2). Ce distributeur (2) comporte un alésage divisé en un réservoir de liquide systémique (6) et un réservoir de liquide échantillon (7). Le réservoir de liquide systémique (6) est relié à la pompe (10), le réservoir de liquide échantillon (7) communiquant avec une buse (15) munie d'un embout de distribution (16). Ladite membrane (5) est pratiquement incompressible, la pompe (10) permettant ainsi de réaliser une distribution précise. L'invention concerne également un système de séparation de gouttelettes par voie électrostatique utilisant une électrode (25) couplée électriquement à l'embout de distribution (16) ainsi qu'une plaque conductrice (19) formant une électrode de réception en dessous d'un substrat (20). Cet ensemble de distribution est particulièrement utile pour des ensembles de distribution à buses multiples.
